In this paper, the control scheme of a distributed high-speed generator system with a total\namount of 12 generators and nominal generator speed of 7000 minâË?â??1 is studied. Specifically, a fault\ntolerant control (FTC) scheme is proposed to keep the turbine in operation in the presence of up\nto four simultaneous generator faults. The proposed controller structure consists of two layers:\nThe upper layer is the baseline controller, which is separated into a partial load region with the\ngenerator torque as an actuating signal and the full-load operation region with the collective pitch\nangle as the other actuating signal. In addition, the lower layer is responsible for the fault diagnosis\nand FTC characteristics of the distributed generator drive train. The fault reconstruction and fault\ntolerant control strategy are tested in simulations with several actuator faults of different types.
